Flower colour in pea plants is inherited genetically. The white allele is recessive, and the pink allele is dominant. A plant that is homozygous recessive is bred with a plant that is heterozygous.

Researchers have developed the first comprehensive atlas of allele-specific DNA methylation across 39 human cell types, revealing a complex landscape of epigenetic regulation. The study identified ...

An oligonucleotide probe, specific for one allele, is hybridized to the target at low temperature. This forms a duplex DNA region that interacts with a double strand–specific intercalating dye.
